             Summary: Prefix_Tree seeks to null if the seeked Cell is greater than the last key in the file
                 Key: HBASE-13944
                 URL: https://issues.apache.org/jira/browse/HBASE-13944
             Project: HBase
          Issue Type: Bug
          Components: prefixtree, Scanners
    Affects Versions: 1.1.0.1, 1.0.1.1, 0.98.13, 1.1.0, 1.0.1, 1.0.0
            Reporter: ramkrishna.s.vasudevan
            Assignee: ramkrishna.s.vasudevan
            Priority: Minor
             Fix For: 2.0.0


When using any DBE other than Prefix_Tree when the internal scanners seek to a key greater than the last key in the file, when we do scanner.getKeyValue() we get the last key in the file, whereas PrefixTree seeks to null.  This is a behaviour change.  May be in the actual scan case we may not end up in this scenario, need to check with a testcase.  But the test in TestSeekTo.testSeekTo() has a clear illustration of this problem. 
Will take this up after the current activities.
